There is no problem to the product itself, the feeling of use is also good. But packing is disappointing. This time I bought two pieces of GC and WA red, whereas the WA red one was wrapped in cushioning material (bubble wrap), whereas this GC was a plastic with only one thin cardboard on one side. Thanks to this, there was a little dent as small finger nails on the side without cardboard. I will use it as it is because there is no problem on the purpose of this time, but I think that I am returning it for the purpose of severe polishing.

With the grinding stone attached to the grinder, the carbide drill blade (monotalou, detailed unknown) was not ground, so it was replaced with a GC grindstone. For GC grinding wheels, the carbide blade can be successfully grounded, but on the contrary, the high-speed blade and the cobalt high-speed blade are excessively ground and can not be finely adjusted (the high-speed blade which is thinner than approximately φ 4 has a contact portion at the time of contact with the grindstone It felt like disappearing).
